Abstract

A polymer blend comprising polyamide, polypropylene (PP) and at least one of poly (lactic acid) (PLA) and a multi-phase compatibilizer comprising PA11-co-PP-maleic anhydride (MA). The polymer blend can be reinforced with hybrid fillers including biocarbon, glass fiber, carbon fiber and nano-clay to create composites useful in the creation of products of manufacture such as auto parts.

First claim

What is claimed is:

1. A composite comprising a polymeric blend of polyamide (PA) and polypropylene (PP) and biocarbon and a melt flow enhancer, wherein the melt flow enhancer is poly (lactic acid) (PLA), and the PLA is 10% wt. or less of the composite.

2. The composite of claim 1 , wherein the composite further comprises epoxidized natural rubber (ENR).

3. The composite of claim 1 , wherein the composite further comprises a filler selected from carbon fiber, glass fiber, a mineral filler, or any combinations thereof.

4. The composite of claim 1 , wherein the PA is selected from the group consisting of: PA 6, PA 6,6 PA 6,10 and biobased PA.

5. The composite of claim 1 , wherein the composite further comprises maleated polyolefin.

6. The composite of claim 1 , wherein the polymeric blend comprises PA 6, PLA, PP and MAPP, and wherein the composite further comprises carbon fiber, epoxidized natural rubber and zinc stearate.

7. The composite of claim 1 , wherein the polymeric blend comprises PA 6, PLA, PP, MAPP and MAPE, and wherein the composite further comprises glass fiber and zinc stearate.

8. The composite of claim 1 , wherein the composite further includes a copper salt thermal stabilizer.

9. An article of manufacture including the composite of claim 1 .

10. An article of manufacture including the composite of claim 2 .

11. An article of manufacture including the composite of claim 3 .

12. An article of manufacture including the composite of claim 4 .

13. An article of manufacture including the composite of claim 5 .

14. A composite comprising a polymeric blend, biocarbon, carbon fiber, epoxidized natural rubber and zinc stearate, wherein the polymeric blend comprises of polyamide 6 (PA 6), polypropylene (PP) and maleated polypropylene (MAPP).

15. An article of manufacture comprising the composite of claim 14 .

16. A composite comprising a polymeric blend, biocarbon, glass fiber and zinc stearate, wherein the polymeric blend comprises polyamide 6 (PA 6), poly (lactic acid) (PLA), polypropylene (PP), maleated polypropylene (MAPP), and maleated polyethylene (MAPE).

17. The composite of claim 16 , wherein the composite further comprises epoxidized natural rubber (ENR).

18. An article of manufacture including the composite of claim 16 .

19. An article of manufacture including the composite of claim 17 .
